LAVATORY-BASIN.

. SPECIFICATION formingpart of Letters Patent No. 249,549,. datedNovember 15, 1881.

Application filed March 31,1881 (No model.)

To all whom it may concern:

Beit known that I, CHARLES E.Ro'1211vso1v, a citizen of the UnitedStates, residing in Brooklyn, in the county of Kings and State of NewYork, have invented certain Improvements in Lavatory-Basins,- lowing isaspecification.

Myinvention relates to stationarylavatories or wash-basins, and has forits objects to improve the present construction and connections of o theseveral parts, and to provide a simple and effective waste or outflowvalve which can be controlled from above the basin, thereby obviatingthe necessity of inserting aplug by hand and removing it by pulling achain, as in the present construction. 1

In the accompanying drawings, Figure 1 is a vertical mid-section of alavatory provided with my invention. Fig. 2 isa plan ofthe same with thebowl proper andslab removed. Fig. 3 is a fragmentary horizontal section,taken on line 3 3 and enlarged; and Figs. 4

of which the foland 5 are enlarged fragmentary detail views,

which will be referred to more particularly hereinafter.

I have shown my improvements .as applied to what is known as theWellington overflow-basin but theyare not of necessity confined to thisform of basin. One portion of the invention relates to the mode offixing the bowl or basin properv in place, and another portion tomechanism for stopping the wasteoutlet from the bowl.

Let Arepresent the usual marble or metal slab; B, the outer bowl-liketrunk, secured by means of a packing-ring, a, to the under side of theslab, and O the bowl proper, a space, I), being left'between the uppermargin of the bowl 0 and the slab, to permit the water from the bowl tooverflow into the trunk B. Generally speaking, this construction is, sofar, the same as that shown in the patentsof D. Wellington, Nos. 102,737and 199,765.

videthe bowl with a tubular support at its botpartially, by sustom only,leaving the upper edge free for the the'bottom ofthe bowl 0, which isgenerally overflow, which is entirely unobstructed. Into made from someceramic material, I fix or set In these patents, however, the bowl issupported a metal bush, 0, provided, by preference, with the usualstrainer, to prevent obstructing substances from getting into thewaste-pipe. This bush has a female screw, which engages a male screw ona tubular stem, 61, as shown. This stemhas a flange, c, which, when thestem is screwed into the bush, clamps a packing-ring, f, against thebowl around the bush. This makes a water-tight joint at the bottom ofthe bowl, and serves also to securelyfix thestem d to the bowl.

. Referringto Fig. 4, which isan enlarged plan view of theapertureginthe bottom of the trunk B, h h are lugs or projections at the margin ofsaid aperture, which lugs serve to engage angularslots i i (see Fig. 5)in the stem d, and form what is usually called a bayonet-joint. Theenlarged view of the stem in Fig. 5 shows this arrangement very clearly.When the stem has been inserted in the aperture gas faras the lugs Itwill permit, the bowl and stem are turned on-theircommon axis until thesaid lugs engage the lateral branches of the slots i, when the partswill be firmly joined together, and the stem can only be released fromits socket by turning backward. The margins of thelateral branches ofthe slots 1 may be slightly beveled orinclined, so as to cause the lugsto draw the stem downward as it is turned, and the stem may have acollar or flange to be drawn down to and firmly seated on the trunk; orthe stem may be screwed into the trunk, but the mode shown is thecheaper.

The above-described mode of attaching the bowl to the trunk leaves thespace between the bowl and trunk wholly unobstructed, gives a firmsupport to the bowl, and permits the bowl to be readily removed andreplaced when this is necessary.

Within the hollow stem cl is a valve-seat, j, adapted to receive avalve, k, which rests normally in said seatand closes the valve apertureor opening through the stem to the wastepipe; and in the wallot' thestem is an aperture, l, through which the overflow water passes. Thisaperture also serves to permit the passage of a lever, m, for liftingthe valve from its seat.

The lever m is fulcrumed at n to some fixed point, preferably to an arm0, which branches from the stem d, and its free end is turned up, so asto take under the valve. Its other end 2 assume is coupled to a rod, 12,the upper end of said rod being attached to aring, g, which encircles astem, a, capable of being turned within said ring by means of a suitablehandle, 8. The stem 1" has a spiral groove, t, cut or formed round it,and with this groove engages the tip of a pin or screw, to, in the ringq. An inclosing-case, c,- which is secured to the slab, forms housingsand bearings for the ring q and the stem r.

The operation of the above-described mechanism is as follows: When thehandle 8 is turned it rotates the stem 4, to which it is attached. Thespiral groove t on said stem acts to drive down the ring q, and this,acting through rod 19 and lever in, lifts the valve is from its seat andallows the waste water to flow off. A reversal of the operation allowsthe valve to again assume its normal position on the valve-seat. Thus itwill be seen thatI avoid the annoyances of the ordinary chain and plugor stopper and provide for an effectual automatic closure of thewaste-outlet.

I have said that the normal condition of the valve is on its seat andthe wasteoutlet closed;

but it is obvious that the valve may be left raised from its seat forany length of time, and this. may be desirable where the water is to beleft running for a time.

To make room for the lever and rod for operating the valve I have showna lateral enlargement or extension, to, of the trunk B but thisis amatter of little importance. In adapt ing my valve and its operatingmechanism to bowls not employing a trunk, B, the said lever and rod maybe arranged in the conduit which extends from the overflow-opening downto the waste-pipe.

Having thus described my invention, I

claim 1. An overflow-basin comprisinga trunk secured to the slab and abowl proper mounted therein on a stem which connects the two at theirbottoms, whereby the space between the trunk and bowl is left entirelyunobstructed, substantially as and for the purposes set forth. 2. Thecombination, with the trunk of an overflow-basin, of the bowl propermounted in the trunk on a tubular stem, which is socketed in thewaste-outlet of the trunk, substantially as and for the purposes setforth.

8. The combination, with the trunk of an overflow-basin, of the bowlproper mounted in the trunk on a tubular stem, which connects thewaste-outlet of the bowl with the wasteoutlet of the trunk, the saidstem provided with a suitable valve-seat, a valve resting in or on saidseat, and a mechanism, substantially as described, arranged in the spacebetween the bowl and the trunk, for lifting the valve from its seat,substantially as set forth.

4. The combination, with the bowl, of the valve arranged to close itswaste-outlet, the lever m, rod 1), ring q, spirally-grooved stem r, andcasing 22, all arranged to operate substantially as and for the purposesset forth.

5. The combination, with the trunk having an outlet, b, provided withlogs or projections h, of the-bowl provided with a tubular stem, cl,having angular slots '1 to engage the projections h on the trunk,substantially as and for the purposes set forth.

6. The combination of the b0wlO,the screwthreaded bush 0, the tubularscrew-threaded stem d, provided with a flange, e, slots 'i, avalve-seat, j, and an aperture, l, for the overflow-water, thepacking-ring or washer, f, the

trunk B, provided with lugs 11., to engage the slots 2' in the stem d,the valve k,and the lever m, actuated from above the slab,to which thetrunk is secured,all arranged substantially as and for the purposes setforth.

7. The combination, with the bowlU, of the valve 70, arranged tonormally close the Wasteoutlet, the trunk 13, provided with an extensionor enlargement to receive the mechanism for lifting the valve, and thesaid valve-lifting mechanism, all arranged substantially as set forth.

In witness whereof I have hereunto signed my name in the presence of twosubscribing witnesses.
